TO. ALL WHOM IT MAY. CONCERN:

Be it known that I, LEANDER W. Bornrox, of the city and county ofHartford, in the State of Connecticut, have invented a new and usefulimprovement in Apparatus or Machinery for Drying or Desiccating Wool,850.; and I do hereby declare that the following is a full, clear, andexact description of the construction, charactor, and operation of thesame, reference being bad to the accompanying drawings, which make purtof this specification, in-whieh- Figure 1 is a. perspective view of thewhole apparatus or machine, showing the doors open for feeding ordischarging the wool, a portion of the perforated periphery of thecylindrical vessel which contains the woel while being dried, thecentral perforated tube, and the outside of the eduction port with thepulleys.

Figure 2 is a plan of the same out vertically through the centre,showing the internal structure of the apparatus.

My improvement consists in making or using a cylindrical vessel, theperiphery of which is finely perfo rated, or made of wire cloth, or anyother analogous substance, with solid or closed ends or heads, and witha finely perforated tube passing horizontally through its centre, toserve as an axis on which it-is to be revolved while in use; and inmaking or using a cylindrical case, (in which I place the vessel withthe perforated periphcry, before named,) with solid or closed heads orends, except where the journals of the a'xis of the internal cylinderpass through andhave their bearings; and with a closed periphery, excepta door for feeding and discharging, (which door should be madeessentially steam-tight,) and an eduction port, which is at the end of afiat tube or spent, in which I lace or fit'an exhausting fan, so thatthe high steam may be let in through the perforated tubular axis, whenit will percolate through the wet wool, and, by its superabundant heat,convert the moisture in the wool into steam, and be all carried outtogether at the ednction port by the action of the exhausting fan,leaving the wool essentially dry. r

I make the external case of wood, or any other suitable material, in acylindrical form, as shown at A A and A A, fig. 1, and indicated insection in fig. 2. I make it solid or close on its two vertical heads orends, except a hole through the centre, as indicated at a, fig. 2, toreceive and serve as bearing for the journals of the axis]: of theinternal orreeeiviug cylindrical vessel B; and I make the periphery A Aclose or solid, except that I make a door in the front portion of theperiphery, as shown at B, fig. 1, and indicated at B, fig. 2, throughwhich I feed or discharge the wool; ahd to the rear portion of theperiphery I fit a suitable flat tube, the outside of which is shown at,C, fig. 1, and its internal structure is indicated in section in fig. 2,where a section of the exhausting fan is also shown at c: andin theextremity of this flat tube 0 is the eduction port at, as shown insection in fig. 2, through which all of the steam, 81.0., is to beexhausted by the operation of the fan 0; and I support this case onlegs, as e e e e, or otherwise. I make the internal cylindrical vesselwith close or solid heads or ends ofwnod, or any other suitablematerial, as indicated at D, figs. 1 and 2, except that I make anaperture in each, as shown at a, fig. 2, in which I secure a hollowshaft, 12, figs. 1 and 2, by which the internal cylindrical vessel is tobe revolved when in use; and I make the periphery of this internalvessel of perforated sheet metal, or of wire cloth, as shown at E,figsfil and 2, or of any other suitable substance, through which thesteam. or vapor will freely pass; and in this periphery I make a door,as shown at G, fig. 1, and indicated at G, fig. 2; and I place thisvesselD within the external case A A, &c., as shown in figs. 1 and 2. Imake the shaft 1;, figs. 1 and 2, by'which the vessel D is to berevolved, of a hollow tube, with its periphery finely perforated, asindicated at b, figs. 1 and 2, so as to allow the high steam (whenadmitted into either end of it, the other end being stopped,) to passinto and till the internal vessel D, while its ends serve as journals,and one of them carries a pulley, as H, fig. 1, on which a belt wor'kstorevolve the internal vessel when it is used. I make the exhaust fan 0 ofa shaft and four or any other convenient number of wings or vanes, andof a sufficient size to successfully exhaust or carry out all of thesteam or vapor which enters or accumulates in the apparatus; and on oneend of the arbor or-shaft I fit a pulley, as g, fig. 1, which is to beoperated or driven by a. belt in the usual way, or any other convenientmeans may be used to operate the fan which will drive it with sutficicntvelocity for the purpose.

Having made and arranged the ports as before described, connected thesteam pipe with-the hollow shaft l: or induction port, vand shipped thebelts in their proper order, I open the doors B and G and fill thecylinder D with wet ornewly-washed wool, and close the doors. The outerone, B, should be closed essentially steam-tight I then put on the powerupon tlfe belts, one of which on the pulley H will revolve the cylinderD slowly, as two or three revolutions in a minute, while the other belton the pulley y will revolve the fun a with suiiicieut velocity toexhaust the case; and I let on the high steam, which will pass throughthe perforations in the hollow shaft 6, and percolate through thewholemass of the wool, and, by its super-abundant heat, it will convert themoisture which is in the wool into steam, and the whole will be carriedout by the exhaust fan a through the eduction port 02, leaving the woolessentially dry. The steam used should he raised to from four to sixatmospheres, (in proportion to the quantity of the wool, &c.,) whenthree or four minutes will be time enough to dry the wool suflicientlyfor carding, 8m Probably it would require about as many minutes by thisprocess as it would hours by any process where the steam is not applieddirectly to the wool. If it be desired to dry the wool so thor oughly asto fit it for packing for storage or transportation, the steam pipe mayhe removed without stopping the motion of the cylinder D orthc fan a,and allow warm air (as of the room) to pass through the wool for a fewminutes, when the desiccation will be complete. I

What I claim as my invention, and desire to secure by Letters Patent, isv The combination of the internal cylindrical vessel D, and itsinduction port a b, with the cylindrical case A A, &c., fan 0, andeduction port d, when the whole is constructed and arranged and made tooperate and produce the result substantially as herein described and setforth.
